Main Methods:

• Review of chemical synthesis approaches for deuterating nucleoside bases (aglycones).
• Discussion of methods for single-site and multiple-site chemical deuteration of sugar moieties.
• Overview of enzymatic synthesis routes for creating deuterated nucleosides and nucleotides.
• Examination of techniques for synthesizing nucleosides labeled with multiple isotopes.

Main Results:

• Established chemical and enzymatic methods allow for controlled deuteration at various positions within nucleosides.
• These synthetic routes facilitate site-specific incorporation into DNA and RNA constructs.
• The reviewed methods support the production of nucleosides labeled with deuterium and potentially other isotopes.

Conclusions:

• A variety of synthetic strategies exist for producing deuterated nucleosides suitable for NMR and biological studies.
• These methods enable the creation of specifically labeled DNA and RNA for advanced molecular research.
